We have a mailbox that is getting rather large and it is being used to dump emails that are later read into our CRM. Recently we have started seeing the below error. Has anyone else had this issue? It looks different then the explanations for the max number of folders open being set to 5. Granted there is a LOT of email being dumped in this folder from multiple sources, sometimes having multiple connections open, and sometime read back out causing this error.
